How to get there   

You have to drive 36 kilometers from the town of Chisec to the town of Raxruhá. In Raxruhá you make a left turn and drive 12 kilometers more on an unpaved road until you reach La Isla community. Keep driving straight 4 kilometers more until you reach La Unión Visitors' Center. There you can park your vehicle and walk one kilometer until you reach the Passion River where you take a small boat (30 minutes) to the archaeological site.   The tour of the site takes about an hour and a half (low effort).
